CVE-2025-54767 is a vulnerability identified in version 8.04 of Xorux's LPAR2RRD product, specifically affecting the Xormon Original virtual appliance component. The vulnerability is classified under CWE-648, which relates to the incorrect use of privileged APIs. In this case, an authenticated user with read-only permissions can exploit the flaw to kill any processes running on the appliance under the 'lpar2rrd' user account. This indicates a privilege misuse where the system fails to properly enforce process control restrictions based on user privileges. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and needs privileges (PR:L) but no user interaction (UI:N). The scope is unchanged (S:U), and the impact is high on confidentiality (C:H) but no impact on integrity (I:N) or availability (A:N). The vulnerability allows an attacker to terminate processes, which could lead to information disclosure or disruption of monitoring functions, but does not directly affect data integrity or system availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The CVSS v3.1 base score is 6.5, indicating a medium severity level. The vulnerability arises from improper API usage that grants excessive control to users who should only have read-only access, potentially exposing sensitive operational data or disrupting monitoring activities by killing critical processes.

For European organizations using LPAR2RRD version 8.04, particularly those relying on the Xormon Original virtual appliance for monitoring and managing virtual environments, this vulnerability poses a risk to confidentiality and operational stability. An attacker with authenticated read-only access could terminate processes critical to monitoring, potentially leading to loss of visibility into system performance or security events. This could delay detection of other attacks or system failures. The confidentiality impact is significant because killing processes might expose sensitive runtime information or logs accessible during process termination. Although availability and integrity are not directly impacted, the disruption of monitoring services can indirectly affect operational continuity and incident response effectiveness. Organizations in sectors with strict compliance requirements (e.g., finance, healthcare, critical infrastructure) may face regulatory risks if monitoring gaps lead to undetected breaches or failures. Since exploitation requires authenticated access, the threat is more relevant in environments where user credentials are shared, weakly protected, or where internal threat actors exist.

1. Restrict read-only user accounts strictly to prevent any process control capabilities; review and harden user privilege assignments within LPAR2RRD. 2. Implement network segmentation and access controls to limit which users can authenticate to the Xormon Original virtual appliance, reducing the attack surface. 3. Monitor process termination events and audit logs on the appliance to detect unusual activity indicative of exploitation attempts. 4. Employ multi-factor authentication (MFA) for all users accessing the appliance to reduce the risk of credential compromise. 5. Engage with Xorux support to obtain patches or updates addressing this vulnerability as soon as they become available. 6. Consider deploying host-based intrusion detection systems (HIDS) on the appliance to alert on unauthorized process terminations. 7. Regularly review and update security policies related to privileged API usage and user access management within virtual appliance environments.
